Critical alerts shouldn't stop at a notification—or voicemail. WakeUp Dev turns Grafana, UptimeRobot, and HTTP webhook alerts into phone calls with press-1 human acknowledgement and automatic on-call escalation. If nobody acknowledges, the alert moves to the next responder. Built as a lightweight, serverless alternative for DevOps and SRE teams. Our official open-source integration scripts for Python, Node.js, and Bash are available on GitHub.
